Kestrel, a Proudly South African product, had developed a reputation across the globe for providing leading edge small wind turbine alternative energy solutions. Kestrel is a subsidiary of Eveready (Pty) Ltd, South Africa’s icon battery manufacturer brand with a proud 70 year old history of providing portable power solutions in South Africa.
The combination of the Kestrel wind turbine technology and Eveready’s ISO certified manufacturing and technical expertise has achieved recognition as Proudly South African Innovator of the Year and Best Exporter. Eveready Kestrel provides small wind turbine solutions in the 600w, 800w, 1kW and 3kW range. Its robust construction and unique engineering makes it the product of choice for telecommunications, off grid, grid connect and water pumping solutions.
The e400n is the latest development in the Kestrel range. The completely new 120 pole single axial flux direct drive alternator incorporates three main shaft bearings for long service life. The e400i maintains rated output in excess wind speeds using Kestrel patented blade pitch control. The e400i therefore gives an optimum energy harvest with no cut out wind speed. This Kestrel, like the other models optimises low wind and stays in complete control whether loaded or unloaded during excessive wind speeds.
